A rodeo clown, a VIP concierge and a fitness superstar all walk into a house...

That is not the beginning of a bad joke; instead, it's the recipe for another exciting season of Big Brother!

On Monday, CBS announced the cast for the 19th installment of the summer reality-competition show that pits 16 houseguests against one another in a quest for $500,000. Oh, and they're also locked in a "house" together with 87 cameras and 100 microphones recording their every move 24 hours a day. The new season kicks off with a two-night premiere on June 28 (8/7c) and continues the following night (9/8c).
